New Comet C/2020 K7 (PANSTARRS)
June 04, 2020
CBET 4790 & MPEC 2020-L09, issued on 2020, June 02, announce the discovery of a comet (magnitude ~20) in four 45-s w-band CCD images obtained with the Pan-STARRS1 1.8-m Ritchey-Chretien reflector at Haleakala. The new comet has been designated C/2020 K7 (PANSTARRS).
We performed follow-up measurements of this object while it was still on the PCCP webpage.
Stacking of 8 unfiltered exposures, 180 seconds each, obtained remotely on 2020, June 02.2 from X02 (Telescope Live, Chile) through a 0.6-m f/6.5 astrograph + CCD, shows that this object is a comet with a compact coma about 6" in diameter and a tail 3" long in PA 306 (Observers E. Guido, M. Rocchetto, E. Bryssinck, M. Fulle, G. Milani, C. Nassef, G. Savini).
MPEC 2020-L09, assigns the following preliminary parabolic orbital elements to comet C/2020 K7 (PANSTARRS): T 2021 Oct. 5.30; e= 1.0; Peri. = 60.84; q = 5.64; Incl.= 34.55
